Raspberry Pi 4 Blank Screen

[kgmoney]

Hi,

I'm using the qlcplus_raspbian_buster_20190825.7z image on the Pi4. When it boots I see the raspberries and the login prompt, but as soon as qlcplus starts the screen goes blank and nothing shows up....running it manually does the same thing. This is with an HDMI monitor. I have also found that if I plug in a different HDMI monitor, it starts up correctly, then if I switch monitors while it's running, it continues to work correctly...until I reboot.

Any thoughts? Are there any logs I could look at?

Thanks,
Kevin
